Incident at Thompson, MB


1997-07-18: The crew of TKR 253 reported inbound from Molson Lake to the Thompson airport with a hydraulic failure. FSS called out the CFR response team including the Thompson Fire Department as the a/c landed safely at 2336Z. The a/c taxied to the MGAS hangar, and there were no delays to other a/c. The crew had ratcheted the bomb bay doors closed and hand pumped the gear down prior to landing. Maintenance later reported that the problem was a shattered check valve in the right wing root which resulted in a complete loss of hydraulic fluid. The check valve is being replaced. UPDATE Maintenance advises that the 3000 psi check valve installed in the high pressure line between the pump and main hydraulic panel had failed. A circumferential split rendered the valve in two pieces, which resulted in a loss of fluid and pressure. The valve has been sent to the Province of Manitoba's main base for further evaluation.
